Firelight 450

The Firelight 450 is a high quality, lightweight down sleeping bag that is ideal for use in temperatures down to -5°C. Please refer to the detailed information on temperature ratings below and click here for help on choosing a bag.

Manufactured wholly in Poland, the Firelight 450 is filled with the famed Polish white Goose down that is 100% ethically recovered (read more here). The down has a fill-power of 900 cubic inches as measured by the EU norm (and is equivalent to 970 cubic inches using the US standard).

The Firelight 450 has a full length zip that lies on the top of the bag. The zip is protected by a single baffle. There is a neck collar that can be adjusted to close completely around the neck to provide a complete seal.

The Firelight 450 comes in three sizes and is supplied with a compact stuff sack and a large storage bag.

The construction describes how the down is held in place (otherwise all the down would fall to the bottom) and what features are incorporated to maximise heat retention or, conversely, regulate your temperature. A bag as light as the Firelight 450 does not need to have sophisticated features as there simply isn't enough down for it to be expected to perform in very cold temperatures (although it is certainly better than having nothing).

Lightweight fabrics allow the down to loft and reduce the weight of the bag. Although there are lighter-weight versions of the Pertex Quantum fabric we are using, they offer a negligible saving in overall weight and, having a lower tear strength, are easier to damage.

The Firelight 450 is an excellent all-round bag. It has enough down fill to be useful for lightweight summer alpine climbing or mountain trekking at altitudes of up to 4000 metres. It is also sufficiently warm for use in spring/autumn, and possibly winter, camping at lower altitudes. We believe this bag to be the most versatile of the range.

In 2005 the European Standard EN 13537 became the official standard for the labelling of sleeping bags in the European Community. The standard is not mandatory.

Although there are four different measurements, the two most useful (and in our experience reasonably accurate) ones are:

EN13537 Comfort rating

Temperature at which a standard adult female can have a comfortable night’s sleep.

EN13537 Lower limit

The lowest temperature at which a standard adult male is deemed able to have a comfortable night’s sleep.
